IMPROVED FURNITURE-(EASTER.

The Schedule referred to in these Letters Patent and making part at the lame.

To all whom 'it may concern Be it known that I, CHARLES G. WILson, of Brooklyn, in the county of Kings, and State of New York, have invented a new and useful Improvement in Furniture-Casters; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- The figure is a detail vertical section of my improved caster.

My invention has for its object to furnish an improved furniture-caster, which shall be so constructed and arranged that it will allow the table or other article to which it may be attached, to be moved freely in any direction, and which shall atthe same time be simple in construction, strong, durable, and not liable to get out of order; and consists in the caster constructed with a sphere and a series of small balls, freely moving over the top thereof, as hereinafter more fully described.

A is the body of the caster, in the upper end of which is formed a socket, to receive the end of the lg of the table or other artic of furniture, or a tenon formed upon said leg.

The caster may be secured in place by means of a screw-thread, out upon the inner surface of said socket, or by means of Si. :ws or rivets, passing through the sides of said socket,

In the bottom or lower part of the bodyA is formed a hemispherical or cup-shaped socket, in which are placeda number of small balls, B, and a single large. central hall, 0. The number of the smallbails B must be such as to nearly but not quitefili the space between the ball C and concave surface of the cavity in which it is placed. The ball 0 must be of such a size that its lower side may project below the lower end of the body A, and it is kept in place by the cap D, which screws upon the lower end of the said body, as shown in the figure.

The cap I) has a hole formed through it, through which the lower part of the ball 0 projects; said hole being made of such a size that the ball 0, when supporting the article of furniture to which the caster may be attached; may not touch the said cap, and at the same time so small that the said 'ball 0 cannot drop through it when the saidarticle'is raised from the door, the friction being entirely borne by the balls B and O, rolling upon each other, and upon the concave surface of the cup in which they are placed.

The outside of the caster may be made of any desired shape, or may be made to correspond with the style of carvin with which the article of furniture to which it may e attached is ornamented.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- The improved furniture caster above describes, formed.by the combination of a solid sphere, rolling freely in its secket, a casterbody, provided with a hemispherical concavity and suitable cap, and a series of frictional balls arranged around the surface of the said sphere, and freely moving over the entire upper surface of the caster-ball, when brought in frictional contact. with the same, all substantially as shown and described.

The above specification of my invention signed by me, this 9th day of J My, 1869.

CHARLES G. WILSON.
